"A tremendous amount of time and effort has gone into pioneering an in-display fingerprint sensor powerful enough to forever change the way you interact with your phone," Lau said in a blogpost detailing the new feature. "It all starts with a new optical fingerprint module, which houses a small lens that can accurately register your fingerprint as it presses down on the cover glass. The screen is used as a light source to enhance the outline of your fingerprint, enabling the sensor to accurately read its exact dimensions and shape. We use a dedicated ‘Trust Zone’ found in the Qualcomm® Snapdragon 845 to store your fingerprint information, which serves as an isolated virtual space for the sake of confidentiality. Whenever Screen Unlock is used, your fingerprint is compared to the information stored in the Trust Zone to ensure authenticity and actively defend against false patterns," he explained.
